Falken Tire is proud to announce the launch of the new Azenis RT615-K. While the original RT615 proved to be a dominant force in the DOT approved and truly street functional competition tire category, we’ve decided to make it even better. The K in the new RT615-K can have many meanings but none describe the second generation 615 better than KAIZEN. By definition, this Japanese word means "continuous improvement" which precisely describes the newest edition to the Azenis lineup. Visually, nearly identical to its predecessor, the subtle K on the sidewall is the only tell tale sign of what lies within its completely revised tread compound.

With an advanced motorsports-grade compound, grip remains strong as tire temps rise. This allows for increased entry and exit speeds on the track, resulting in improved lap times, as well as better handling and control on city streets and freeways.In addition, the special 8/32nd molded tread design reduces the new tire’s tread squirm while providing efficient mileage for street use, and a solid center rib significantly reduces wheel spin by trimming the contact patch void ratio under heavy acceleration.Even with an 8% reduction in unsprung tire weight, the Azenis RT-615K performs well in the wet, with optimized aqua tusk positioning that allows better tread adhesion as it delivers ample wet grip performance. Accordingly, wet weather speeds can be achieved and maintained as potential hydroplaning tendencies are reduced.Falken’s engineers recognized the tremendous demands placed on the Azenis RT-615K, so the focus continues on strengthening its versatility and multiple capabilities to deliver the strongest performance tire for street and track conditions.
